Demaryius Thomas had Stage 2 C.T.E. when he died

It’s been nearly eight months since Denver Broncos legend Demaryius Thomas died suddenly at the age of 33. Doctors at Boston University noted DT had Stage 2 C.T.E., but they believe the likely cause of death was due to seizure.

On Tuesday, doctors from Boston University announced that Thomas was posthumously diagnosed with Stage 2 C.T.E., but his life and death were also complicated by seizures brought on by a 2019 car crash. They attacked with little or no warning and led Thomas to wreck other cars and fall down steps.
